The 'Kate Effect' Still Going Strong: Another Designer Dress Sells Out

Catherine Duchess of Cambridge had a big weekend of official royal responsibilities, helping her grandmother-in-law, Queen Elizabeth celebrate her 90th birthday.

As per usual, there was immense interest in what the Duchess was wearing, and as has become the norm, the Roksanda Ilincic dress she wore to attend the Queen’s birthday street party has already sold out.

The colour-block wool-crepe dress, originally $1882, was marked down to $941 however savvy copy-Kate’s were too quick and now it is no longer available.

This latest sell-out, (while it was on sale, we wouldn’t exactly call $941 a steal) cements any questions around whether the ‘Kate Effect’ is still as strong as it once was.

The next day, Kate followed up her winning look with a tried and tested Catherine Walker coat dress which she previously wore in 2011 during the Royal Tour of Canada.

Attending the annual Garter service, the Duchess matched the frock to her Lock & Co. fascinator, Alexander McQueen clutch and the Robinson Pelham diamond earrings – the same ones she wore on her wedding day.

Kate has been on somewhat of a sartorial streak this week, wowing in a $6,000 cobalt blue Roland Mouret cut-out gown to attend the SportsAid 40th anniversary event at Kensington Palace on June 9.
